T43 won't turn on

[agga]

I see a similar post below, but I may as well try again.

Symptom: I press power, dashboard lights flash on, fan turns on, only dashboard lights remaining are the power light and the battery light. Nothing else.

Starting last week, this T43 wouldn't wake up from hibernate. Actually, it did if I pulled the battery out and waited, but I wasn't sure if this was superstition or not.

Finally, it wouldn't come on and I panicked, thinking the motherboard was dead, so took it to a shop. Of course, it works for them, they lamely say hardware is fine, hibernation is problematic, something about a power loop, updating drivers, etc.; basically just told me not to hibernate it anymore, just shut it down from now on.

This worked for about 4 days; now, on turning the computer on I get the same deadness, fan and power lights only. Happened last night and I got it back. Now it seems permanent. No battery-pulling-and-waiting is doing the trick now.

Tell me the shop guys flaked and I need a new motherboard; I'm still under warranty, I guess I could get parts replaced. Or, tell me something else is wrong. Please! How do I make sure it gets fixed next time??

If it comes up functioning again, run pc doctor diags from the bootable cd.
The next time it dies, do not restore its operation and call Lenovo for warranty service. They will probably replace the motherboard.

Oh yes, Welcome to the forum...

all right, i'll see how that goes, thanks- i figure I'll just go back to the shop and instruct them to replace the motherboard whether or not they can figure it out.

now then, I just got it to start by turning it on, letting it do its failure-to-start thing, then rapidly turning it off and then on again. is this likely to cause further damage to the computer?

That seems like your CMOS battery has run out. Have you tried relacing it?
